So weird. I'm taking my car back to BMW and telling them to see why it's so loud. I didn't hear it the first few days but now I hear it every time it opens and closes. I'm probably going to mod it, but will just need to remember to remove the mod when I take the car back every onc ein a while.
On the 128i, I don't think that the change in backpressure will have any effect, I don't have any turbos to spool, I just want a deeper sound at low RPMs
